no, but the thing is that you produce a lot of releases, wich is great of course, but way to many to keep up with...

so it would be comfortable for me, and i suspect most people, to be able to quickly assess if there is an important release, without having to read through all the latest, say, 20 announcements in order to figure that out.

maybe a "security announce mailinglist" would be even more appropriate. many other projects have them.
